Abstract

"ADITIVO DE REDUçãO DE RETRAçãO PARA COMPOSIçõES DE CIMENTO". Um método para reduzir a retração por secagem de uma composição de cimento para a qual foi adicionada água e a composição depositada, compreendendo a adição à composição, antes da sua colocação, de pelo menos um composto de siloxano que é pelo menos de um tipo entre líquido e solúvel, em pelo menos um composto entre água e álcali aquoso."RETRACTION REDUCTION ADDITIVE FOR CEMENT COMPOSITIONS". A method for reducing the drying shrinkage of a cement composition to which water has been added and the deposited composition, comprising adding to the composition, prior to placement, at least one siloxane compound which is at least one of a kind. liquid and soluble, in at least one compound between water and aqueous alkali.
